Malleable Iron End Plug is a essential piping fitting engineered to securely seal the end of threaded pipes—preventing fluid leakage and shielding pipe interiors from debris. Forged from high-grade malleable iron, it delivers reliable performance across residential, commercial, and industrial systems, with two distinct surface options to align with your project’s needs.
Material: Ductile Iron QT450-10
Surface: Black and GLA
Approvals: UL/ FM/ ISO9001
- Robust Malleable Iron Build: Crafted from premium malleable iron, this plug offers exceptional tensile strength and impact resistance, ensuring stable, long-lasting sealing under pressure.
- Precision Threading: Uniform, precisely machined threads create a tight, leak-proof seal when paired with standard threaded pipes, eliminating costly spills or system disruptions.
- Easy Operation: The integrated square drive top enables quick installation/removal via common tools (e.g., wrenches), simplifying on-site work.
- Wide Compatibility: Works seamlessly with various media, including water, gas, heating fluids, and general industrial liquids.
We provide two finish variants tailored to different application scenarios:
Galvanized Finish
- Hot-dip galvanized coating adds superior corrosion/rust resistance, making it ideal for outdoor, damp, or high-moisture environments (e.g., outdoor plumbing, municipal water systems).
- Boasts a clean silver metallic appearance and extended service life in harsh conditions.
Black Raw Finish
- This is the uncoated, as-fabricated state of the malleable iron (no additional surface treatments applied)—the plug arrives exactly as it does post-manufacturing, with a natural dark matte iron appearance.
- A cost-effective choice for dry indoor environments or applications where no special surface treatment is required (e.g., indoor workshop pipelines, temporary sealing setups).
Ideal for:
- Sealing unused pipe ends in residential/commercial plumbing
- Industrial pipeline maintenance/modifications
- HVAC fluid distribution systems
- Municipal water/gas networks
- Temporary pipe sealing during construction or repairs
- Available in all standard pipe sizes (custom dimensions/thread standards available on request)
- Compliant with industry quality norms (e.g., ANSI, DIN) for consistent, safe performance
- Fully compatible with standard threaded malleable iron piping components
